How do I write a good cover letter with the AI?

For the best cover letter, select "Cover Letter" as the type, then describe the position you're applying for, your key qualifications, and why you want the role. Add your name as sender and the hiring manager's name as recipient, choose a Professional or Enthusiastic tone, and the AI will craft a compelling letter.

Can I edit the generated letter after it's created?

Absolutely! The generated letter is a starting point. Copy it to your clipboard or download it, then edit it in any word processor to personalize it further. The AI gives you a solid professional foundation to build upon.

How accurate and professional are the generated letters?

Our AI uses OpenAI's GPT-4.1 model. The letters are well-structured, grammatically correct, and follow proper letter-writing conventions. The quality depends on the detail you provide in your description.

Do I need to provide sender and recipient names?

No, sender and recipient fields are optional. If you leave them blank, the AI will use placeholder text like [Your Name] and [Recipient Name] that you can easily replace. For more personalized letters, providing real names produces better results.
